2 days of virtually continous rain and very mild night temps have the river Nevis in spate. Afternoon temps are 6oC on A Mor summit and 7-8oC at the remaining snow patches! We really need the weather to settle down soon.

The weather is reminiscent of last years autumn conditions thus far with high temps and cloud cover preventing o/night freezing.

I remain fairly optimistic with Nevis(due to observed depth) but A Mor is very doubtful for survival this year and A Beag has got to be somewhere in the middle.

The sun is now lower in the sky and the remaining snow is therefore exposed to less rays but mild,damp nights are the killer as the patches reach the critical time of year.

The forecast is still quite unsettled and mild up to Friday in the west.

Thanks very much: very useful indeed. Maybe a couple of nights' temperatures in low single figures might toughen this patch up! I believe this is the patch that lasted through to the new snows in 2002. That year, lasting snow arrived on the 12th October. If the same happens this year then there's a chance this one will survive if the weather is cool, although I'm guessing it'll be gone by early October. As a guide, this patch was 40m x 12m on the 28th September 2002: larger by some distance, and a week older than your measurements.

coaster, not good news not being able to see Aonach Mor. The recent warm weather has devastated the west's patches, and I'm now doubtful any of them will make it through to the first lasting snows.

Gone.....?! I counted 5 patches.....! Looks like Garbh Uisge Beag is the best bet for lasting - good to see it hanging in there. Unfortunately, haven't seen any long term forecasts pointing at any coolish, lasting weather in October, so I reckon GUB will kick the bucket some time in October! Possibility of only Braeriach making it this year.....?

I noticed that the summit temp at CM was below 0C first thing this morning. With a few cooler days to come this week then that might help to firm up what still remains.
Would it be the case that snowpatches would create their own micro climate, in terms of temperature. If they do, then temperatures of a degree or two above freezing in the surrounding areas might lead to a freeze within the area of a snowpatch...or is this just 'clutching at straws'
Some suggestions of a colder snap around the beginning of next month...helpful? if it comes off.

Coaster and Firefly. The patches around Aonach Mor and Aonach Beag are still intact. Was out today and enjoyed superb weather, Sunny and no wind. There is still a patch on the Ben - see pic - most likely the Observatory area.

Aonach Mor still has its 'Pro Tallus' patch see pics.

Took a wander down over to Aonach Beag - as I hadn't done this Munro before. On the col between Aonach Mor and Beag - down the corrie I could see a sizeable patch. After doing the Munro, I descended the corrie towards this patch. I was suprised how low down it was and how difficult it was to get to. Treacherous is describing the route down lightly - Despite the Summery conditions I can tell you that the patch was rock hard. So hard that I couldn't walk on it with my trail shoes. Anyway enjoy these pics of a sizeable patch that will almost certainly last the year.

Nice one snowpatch! The Aonach Beag patch is quite something considering it's low elevation. Good shot of the Ben too; it still looks pretty healthy. The Aonach Beag patch doesn't appear to have changed too much from the pictures from earlier this month (coaster's?) - maybe the west coast will see some survivals after all.....!
